With innovative designs from some of the best architectural talent on Earth, the Yongsan International Business District in Seoul, South Korea is shaping up to be one of the most exciting skyscraper developments in the world. This week saw the unveiling of yet another pair of boundary-pushing skyscrapers - the Velo Towers by New York-based Asymptote Architecture. The striking towers consist of a series of stacked, rounded masses that are topped with roof gardens and connected near the top by a large skybridge.

Asymptote Architecture‘s round, offset Velo Towers offer an interesting alternative to typical skyscraper designs, resembling rotating parts on a machine. Both the interior residential units and external facades have been designed to be built using prefabricated parts. The skybridge, which is located 30 stories above ground, will contain common amenities, including fitness and recreation facilities, lounges, and a landscaped garden.

“By breaking down the scale and massing of the two distinct towers into interconnected circular and oblong volumes, the Velo project proposes an alternative architectural and urbanistic response to the repetitive and monolithic austerity of conventional tower design,” explains Asymptote Architecture. “The recombination of the typical tower form into a new horizontal and vertical configuration enables the formation of a socially engaging and dynamic environmental response.”

Skybridges and twin towers figure to be common design themes in the Yongsan Business District. The Velo Towers will be located near MVRDV’s controversial Cloud Towers (which some say resemble the 9/11 terrorist attacks), as well as BIG’s interlocking Cross # Towers. The new commercial center is expected to be completed by 2024.
